Consider two long concentric cylinders. The inner cylinder has a diameter of 0.20 m and emissivity of 0.44. The inner cylinder temperature is 520 C. The outer cylinder has a diameter of 0.63 m and emissivity of 0.67. The outer cylinder temperature is 330 C. There is a radiation shield between the two cylinders. The radiation shield diameter is 0.30 m and the emissivity of the shield is 0.23. Determine the ratio of radiation heat transfer rate per unit length of the cylinders between the two cylinders with shield and without the shield.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
